Amanita phalloides is the type species of Amanita section Phalloideae, a group that contains all of the deadly poisonous Amanita species thus far identified. Most notable of these are the species known as destroying angels, namely A. virosa, A. bisporigera and A. ocreata, as well as the fool's mushroom .
The genus Amanita was first published with its current meaning by Christian Hendrik Persoon in 1797. [1] Under the International Code of Botanical Nomenclature, Persoon's concept of Amanita, with Amanita muscaria (L.) Pers. as the type species, has been officially conserved against the older Amanita Boehm (1760), which is considered a synonym of Agaricus L. [2]
Although poisonous, death due to poisoning from A. muscaria ingestion is quite rare. Parboiling twice with water weakens its toxicity and breaks down the mushroom's psychoactive substances; it is eaten in parts of Europe, Asia, and North America.
Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species. The most common reason for this misidentification is a close resemblance in terms of color and general morphology of the toxic mushrooms species with edible species.
The destroying angel (Amanita bisporigera) and the death cap (Amanita phalloides) account for the overwhelming majority of deaths due to mushroom poisoning. The toxin responsible for this is amatoxin, which inhibits RNA polymerase II and III. Symptoms do not appear for 5 to 24 hours, by which time the toxins may already be absorbed and the ...
Amanita bisporigera is a deadly poisonous species of fungus in the family Amanitaceae.It is commonly known as the eastern destroying angel amanita, [3] the eastern North American destroying angel or just as the destroying angel, although the fungus shares this latter name with three other lethal white Amanita species, A. ocreata, A. verna and A. virosa.
Amanita virosa is a species of fungus in the class Agaricomycetes. In the UK, it has the recommended English name of destroying angel [1] and is known internationally as the European destroying angel. [2] Basidiocarps (fruit bodies) are agaricoid (mushroom-shaped) and pure white with a ring on the stem and a sack-like volva at the base. The ...
The lethal dose of amanitoxins is 0.1 mg/kg of body weight of humans. The average Amanita mushroom contains 3–5 mg of amanitoxins, so one 40–50 g mushroom could kill an average adult. [1] The U.S. Occupational Safety and Health Administration (OSHA) permits a time-weighted average exposure of up to 5 mg/m 3 of β-Amanitin dust. [2]
